CUFF-BUTTON.

Speccaton of Letters Patent.

Patented Dec. 3, 1912.

Application led November 21, 1911. Serial No. 661,479.

To all whom it may concern:

Be it known that I, HENRY C. JOHNSON, a citizen of the United States,residing at Astoria, Long Island City and State of New York, haveinvented certain new and useful Improvements in Cui- Buttons, of whichthe following is a specification.

This invention relates to cuff buttons.

The object of the invention resides in the provision of a cud buttonparticularly adapted for holding together the ends of cuifs formed ofunstarched fabric, said button including in its structure a clampingmember adapted to be operated on the stem of the button to clamp thefabric at one end of the cuff between the same and the outer head of thebutton whereby accidental disengagement of the button from the cuff andpossible loss of the button is guarded against.

A further object of the invention resides in so constructing the outerhead of the button and the clamping member that when the clamping memberhas been operated to full clamping relation with respect to the fabricthe elasticity of the latter will serve as a means to lock the clampingmember against movement from clamping position.

With the above and other objects in view, the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is aside elevation of a culi' button constructed in accordance with theinvention, Fig. 2, a longitudinal section of what is shown in Fig. 1,Fig. 3, a section through the button hole at one end of an iinstarchedcuff showing the button applied, certain parts of the button being insection and the clamping member positioned in full clamping relation tothe fabric of the cuff, Fig. 4, a view similar to Fig. 3 with certainparts of the button in section and the clamping member positioned toshow the compression of the fabric that would arise when the clampingmember is moved from full clamping position shown in Fig. 3, the

elasticity of the fabric serving to resist such compression and therebylocking the clamping member against movement from full clampingposition, and Fig. 5, a section on the line 5-5 of Fig. 1.

`Referring to the drawings the button is shown as comprising an outerhead 10, an inner head 11 and a shank 12 connecting said outer and innerheads. The outer head 10 is of substantially elliptical formation andhas its inner face dished as at 13. The shank 12 is threaded as at 14and movable on this threaded portion of the shank is a clamping member15 whose long axis is of greater length than the short axis of the outerhead but of less length than the long axis of said outer head.

In applying the button the fabric at one end of the cuff is disposedbetween the outer head 10 and the clamping member 15, while the fabricat the other end of the culi' is disposed between the clamping member 15and the inner head 11. When the button is thus associated with the cuffit is only necessary in order to secure the button against accidentaldisengagement from the cuff and possible loss, to operate the clampingmember 15 toward the outer head 10. During the `final movement of theclamping member toward the outer head and when the long axis of theclamping member is disposed parallel to the short axis of the outer headthe fabric will be compressed between the clampingmember and outer headso as to resist further movement of the clamping' member. Thisresistance however is manually overcome and the clamping member is movedto the position shown in Fig. 3 when the button will be secured to t-hecuff in a manner that will provide against accidental disengagementthereof. When the clamping member is disposed in the position shown inFig. 3 movement thereof away from clamping position would result in acompression of the fabric between same and the outer head, but as suchcompression of the fabric is resisted by the elasticity of the latter,such elasticity will serve to efficiently lock the clamping memberagainst accidental movement fromfull locking position.

What is claimed is:

The combination with a cuff button including a threaded stem and a headhaving its under face dished, said head having a maximum and a minimumtransverse dimension, of a clamping member screwed on to In testimonywhereof I ax my sgnat the stem and adjustable thereon into and ture, inthe presence of tWo Witnesses. out of the concavty of the head saidclamping member being longer than the minor di- HENRY C' JOHNSON'mension and shorter than the major dmen- Witnesses: sion and narrowerthan the minor dimension FRANCIS BoYLE, of the head.
